OIL-GUARD ATTACHMENT FOR SEWING MACHINES.

Application filed March 17, 1926.. Serial- No. 95,497.

This invention relates to improvements in oil guard attachments forsewing machines.

The principal object of the invention resides in an attachment forsewing machines for preventing oil from the fly wheel from splashingupon the operator when the machine is in operation and to also protectthe goods being worked upon from becoming soiled, as it is a commonoccurrence in factories using sewing machines to suffer heavy losses duetovthe soiling of the goods from this oil.

Another object of the invention is to provide an oil guard for sewingmachines in which any oil which might be thrown from the fly wheel bycentrifugal force is trapped and absorbed.

A further object is the provision of an oil guard which is permanentlyattached to the table of a sewing machine, and which includes aswingable section which when locked in a closed position serves toenclose the fly wheel, but which section may be readily swung back tothus expose the fly wheel when desired to oil the same or to adjust thethread in the machine.

A still further object of the invention is to construct an oil guardwhich may be applied to machines now in use without altering theconstruction of the same, and which is simple in construction,inexpensive of manufacture, and eflicient for the purposes intended.

With these and other objects in view, the invention resides in certainnovel construction and combination and. arrangement of parts, theessential features of which are hereinafter fully described, areparticularly pointed out in the appended claims, and are illustrated inthe accompanying drawing, in which Figure 1 is a perspective view of myimproved oil guard in position upon a sewing machine.

Figure 2 is a vertical sectional view therethrough showing in dottedlines the position of the guard when moved to permit access to the flywheel.

Figure 3 is a perspective view of the oil guard per se.

Referring more particularly to the drawing, the reference numeral 10designates a portion of a sewing machine which includes a table 11 andabove which the usual fly wheel 12 is disposed. The fly wheel is drivenin the usual manner and it is the object of this invention to preventoil used for lubricating purposes from being thrown from the fly wheeland on to the goods being worked upon, as the wheel rotates.

My improved oil guard is constructed of flat resilient material and isdesignated in its entirety as at 13 and comprises what I shall term astationary part ll and a swing able part 15. The stationary part 14:comprises a horizontally disposed flange or foot 16 through whichfastening elements in the nature of screws 17 are passed and which enterthe table 11. Extending upward from the flange is an angularly disposedleg 18.

The part 15 is inverted V-shaped in side elevation and comprises arelatively short leg 19 which is hingedly connected to the leg 18 of thestationary part as at 20. The other diverging leg 21 of the part 15terminates in an angularly disposed flange 22 provided with notches 23extending inwardly from the outer edge, and which receives and coactswith headed studs 24 projecting from the table top.

From the description thus far, it will be seen that the guard isdisposed in alignment with respect to the fly wheel so as to surroundthe same thereby to prevent the splashing of oil during rotation of thewheel. In the event that it should be desired to oil the fly wheel oradjust the thread in the machine, the section 15 may be swung back uponthe hinge 20 as shown in dotted lines in Figure 2 of the drawing, toexpose the fly wheel and permit uninterrupted access thereto. To allowthe part 15 to swing back, it is first necessary to push in upon the leg21 which flexes the same until the notches 28 are free of the studs 24.The part 15 may now be swung about its hinge joint and is supported inits backward position by resting upon the table 11.

For the purpose of collecting any oil which might be thrown upon theinner faces of the guard, I provide a set of prongs 25 on the leg 18which are bent from the material and are upturned, while a set ofdownturned prongs 26 are stamped and bent inward from the leg 21. Theseprongs support oil waste or other absorbent material 27 for absorbing orsucking up any oil which may tend to pass down the inner walls of theguard. When the waste 27 becomes soaked, the same may be removed andreplaced by a fresh supply.

While I have described what I deem to be the most desirable embodimentof my invention, it is obvious that many of-the details may be variedwithout in any way departing from the spiritof my invention and'Itherefore do not limit myself to the exact details of constructionhereinset' forth norto anything less than the whole of my inventionlimited only by the-appended claims table of sewing machine, an oilguard of lnverte'd' V sl'i'ap'e in configuration and adapted to" receivethe'fly wheelof a sewing machine,-- meansfor swingablyf mountsaidoil-guard upon saidtable', aflange p'rovided on th'e i reeend ofsaidguard and co-aeting means between'sa'id guardand said table for lockingthe-former against swinging movement; said co-actin'g means includingspacedstuds extending from' s'aid supporting structure; for reception inrespective notches provided in said flange.-
